Abstract

The invention belongs to the technical field of medical detection, and particularly relates to a rapid radix isatidis (R,S)-epigoitrin content measurement method. The method comprises the following steps: S1, raw material processing; S2, warm immersion and extraction; S3, content determination; S4, model establishment; and S5, analysis and detection. The method is fast and accurate and high in precision, can be applied to rapid test in laboratories and online detection of extract liquid and intermediate products in production process, and can ensure the quality of Chinese traditional medicineextracts and improve production efficiency.

Description

technical field [0001] The invention belongs to the technical field of medical detection, and in particular relates to a method for rapidly measuring the content of Radix isatidis (R,S)-Gaoyichun. Background technique [0002] Radix Isatidis is the dry root of the cruciferous plant Isatis indigo, which is excavated in autumn, removed from the sediment, and dried in the sun. Bitter in the mouth, cold, GUIXIN, Stomach Meridian. Heat-clearing and toxic substances removing, cooling blood and relieving sore throat. It is used for febrile epidemic disease, fever, sore throat, febrile toxin rash, mumps, rotten throat Dansha, big head plague, erysipelas, and carbuncle. Radix isatidis is one of the traditional antiviral Chinese medicines, and Chinese patent medicines based on it have played an important role in combating SARS, influenza A and other febrile epidemics. Modern studies have found that the anti-inflammatory and antibacterial components in Radix isatidis are mainly (R,S...
